Example one

It should be noted that, in the embodiments of the present invention, a data processing method based on a block chain technology is provided, where generation of basic block unit information is taken as an object, and plaintext to be encrypted, including complex and variable length information and fixed length information, is classified, so that the complex and variable length information in the plaintext can become fixed length information after being processed by data (fixed length calculation (Hash) algorithm)) and becomes partial information of the basic block unit information, thereby providing a guarantee for the proof and non-falsification of the plaintext entering a block chain; the tile base unit information may be understood herein as the tile chain transaction information in the tile chain.

Fig. 1 is a flowchart of a data processing method based on a block chain technique according to an embodiment of the present invention. Fig. 6 is a schematic information flow diagram of generating basic unit information of a block according to an embodiment of the present invention. Referring to fig. 1 and fig. 6, a data processing method based on the block chain technique according to an embodiment of the present invention includes the following steps:

s101, collecting and summarizing information from information sources;

collecting and summarizing relevant information (information 1, information 2, …, information m, wherein m is a positive integer) from an information source of the spare data of the memory block chain, wherein the information comprises fixed-length information and complex and variable-length information;

s102, classifying the information according to the attribute of the information, and processing data of the classified different types of information;

classifying the collected and summarized information according to whether the information is of a fixed length type and relevant attributes of importance, and performing data processing on the classified different types of information; specifically, the process of classifying and processing data of the collected and summarized information is as follows:

identifying information which is marked with a fixed-length type and has an importance degree attribute as first-class information (M1, M2, … and Mt, wherein t is a positive integer), and because the first-class information has the fixed-length type attribute and is the fixed-length information, the block chain technology can directly process the information, and therefore the first-class information can be directly written into the block basic unit information; it should be emphasized here that the attribute of the importance degree of the information can be determined by the overall planning according to the product requirement and/or the product definition, and will not be described in detail below;

identifying information marked with non-fixed length type and/or non-importance degree attribute as second type information (m1, m2, …, mt ', wherein t' is a positive integer), wherein the second type information has the non-fixed length type and/or non-importance degree attribute, so that the block chain technology cannot completely and directly process the information, fixed length calculation needs to be carried out on the second type information, and the second type information after fixed length calculation is written into the block basic unit information; it should be emphasized that the information of the fixed-length type and the non-importance degree attribute included in the second type information having the non-fixed-length type and/or the non-importance degree attribute, although having one side of the fixed-length type attribute but limited by the non-importance degree attribute, cannot be directly written into the block elementary unit information; the fixed-length calculation mentioned in the embodiment of the present invention may be an abstract calculation (i.e. a Hash (Hash) algorithm) in the field of computer secret codes, and is mainly characterized in that an input with any length can be changed to obtain an output with a fixed length, and it can be understood and anticipated by those skilled in the art that a related algorithm that can change an input with any length to obtain an output with a fixed length can be adopted by the embodiment of the present invention, and belongs to a protection range supporting and explaining "fixed-length calculation"; the Hash (Hash) algorithm is used as a fixed-length calculation (the fixed-length calculation is preferably the Hash (Hash) algorithm), and the Hash (Hash) algorithm has an irreversible property, so that the non-tamper property of the basic unit information of the block is ensured, and the reliability of the data in the block chain database is greatly improved.

S103, packaging the processing results of the information of different types to generate block basic unit information.

Packing the first type information (M1, M2, …, Mt, where t is a positive integer) written in the block elementary unit information and the second type information after fixed-length calculation, and combining to generate the block elementary unit information.

Specifically, it should be noted here that the fixed-length calculation of the second type of information may include the following several ways, and one of them may be selected according to actual demand conditions:

the first mode is as follows: and merging all the second-type information (m1, m2, … and mt '), and performing fixed-length calculation Hash (m1, m2, … and mt') on the merged second-type information. That is, the second type information (m1, m2, …, mt ') as a whole can output the existence certification of all the second type information (m1, m2, …, mt ') after being merged after the operation of the Hash (Hash) algorithm, and the existence certification Hash (m1, m2, …, mt ') is written into the block basic unit information as a part of the block basic unit information;

the second mode is as follows: and performing fixed-length calculation on each second type of information to obtain presence certificates of each second type of information by Hash (m1), Hash (m2) … and Hash (mt '), and merging all the presence certificates (Hash (m1), Hash (m2) … and Hash (mt')). That is, each piece of information in the second type of information (m1, m2, …, mt ') is separately operated by a Hash (Hash) algorithm, and then the existence certifications (Hash (m1), Hash (m2) … and Hash (mt')) of all the second type of information (m1, m2, …, mt ') are combined, and the existence certifications (Hash (m1), Hash (m2) … and Hash (mt')) are written into the block basic unit information as a part of the block basic unit information;

the third mode is as follows: grouping all the second-type information (m1, m2, …, mt '), the grouping rule can be determined according to the definition of product requirement, the correlation of information and the like, wherein each group comprises at least one piece of the second-type information, and at least one group contains a plurality of pieces of the second-type information, for example, grouping the second-type information (m1, m2), …, the second-type information (mt'); merging the second type information (m1, m2) in the packet containing a plurality of second type information, wherein the merging step is not executed for the packet containing single second type information, and the merged second type information (m1, m2), … and second type information (mt ') in each group are processed by fixed-length calculation of Hash (m1, m2) … and Hash (mt') to obtain the existence certification Hash (m1, m2) … and Hash (mt ') of the second type information in each group, and all the existence certification Hash (m1, m2) … and Hash (mt') are merged. In other words, the second type information (m1, m2, …, mt ') is grouped according to the grouping rule, taking grouping the second type information (m1, m2), …, second type information (mt ') as an example, information in the group of the second type information (m1, m2) is merged, and then the operation is performed by the Hash (Hash) algorithm in units of the grouping, and then the existence certifications (Hash (m1, m2) …, Hash (mt ')) of all the second type information (m1, m2), …, second type information (mt ') are merged, and the existence certifications (Hash (m1, m2) …, Hash (mt ') are written into the block basic unit information as a part of the block basic unit information;

in summary, according to the above differences in the ways of performing fixed-length calculation on the second type of information, the first type of information (M1, M2, …, Mt, where t is a positive integer) written into the block elementary unit information and the fixed-length calculated second type of information are packaged, and the block elementary unit information generated by combining them may include the following forms:

the first form: tile elementary unit information (M1, M2, …, Mt; Hash (M1, M2, …, Mt'));

the second form: tile elementary unit information (M1, M2, …, Mt; (Hash (M1), Hash (M2) …, Hash (Mt')));

the third form: chunk elementary unit information (M1, M2, …, Mt; (Hash (M1, M2) …, Hash (Mt'))).

EXAMPLE six

The above embodiments have elaborated on a data processing method, apparatus and system based on the blockchain technique; the embodiments of the present invention will be further described by way of specific applications.

In practical applications, the data processing method based on the block chain technology in the above embodiment is specifically described by taking my house letter system (hereinafter referred to as house letter) as an example.

The house property information data source of the house letter comprises a self-built house property credit database and a house administration database, wherein the self-built house property credit database at least stores house property information data obtained by house letter users, developers, second-hand house transaction intermediaries, house information consultants and the like, and also stores house property information data such as real residence information, water and electricity charge information, property charge information, family conditions and the like of residents; in other words, the self-built property credit database mainly stores property information data to be imported to the block chain of the house credit central platform. It should be noted here that the establishment of the property information data source related to house trust is the first step of house digitization, and is also a precondition for achieving the purpose of releasing the property liquidity and completing the credit conversion.

As to how the basic unit information of a block in the house credit central platform is generated and how a new block is added to the block chain, as shown in fig. 8, which is a schematic structural diagram of the block chain of the house credit central platform according to a sixth embodiment of the present invention, the basic unit information of a block in the block chain of the house credit central platform can be understood as important structural information related to house property through the following description:

first, property information data from a property information data source from a property credit database and property information data obtained by establishing an information connection with a property administration database are collected.

Secondly, classifying the property information data according to the property of the property information data, and processing the classified different types of property information data; specifically, the property information data which can be identified and marked with the fixed length type and the importance degree attribute is first type information (can be important information related to property valuation, and comprises a serial number of a property certificate of property; identifying the property information data marked with the non-fixed length type and/or the non-important degree attribute as second type information (such as property information data obtained by house letter users, developers, second-hand house transaction facilitators, house information consultants and the like), wherein the property information data obtained by the house letter users, the developers, the second-hand house transaction facilitators, the house information consultants and the like have the non-fixed length type and/or the non-important degree attribute, the block chain technology cannot comprehensively and directly process the type information, the fixed length calculation needs to be carried out on the type of property information data, and the type of property information data after the fixed length calculation is written into the property related to important structural information; it should be emphasized here that the information of the fixed-length type and the attributes of unimportance included in the property information data having the attributes of non-fixed-length type and/or non-importance degree, although having one side of the fixed-length type attribute but limited by the attributes of unimportance degree, cannot be directly written into the property related to important structured information; it should be emphasized that the attribute of the importance degree of the information can be determined by the overall planning according to the product requirement and/or the product definition, and will not be described in detail below; the fixed-length calculation mentioned in the embodiment of the present invention may be an abstract calculation (i.e. a Hash (Hash) algorithm) in the field of computer secret codes, and is mainly characterized in that an input with any length can be changed to obtain an output with a fixed length, and it can be understood by those skilled in the art and is anticipated that any relevant algorithm that can change an input with any length to obtain an output with a fixed length can be adopted by the embodiment of the present invention, and belongs to the protection range of supporting and explaining "fixed-length calculation"; the Hash algorithm is used as fixed-length calculation (the Hash algorithm is preferably selected for fixed-length calculation), and the Hash algorithm has an irreversible characteristic, so that the non-tamper property of the house property related to important structural information is ensured, and the reliability of data in the house trust central platform block chain database is greatly improved.

Then, the first type information (which can be important information related to property valuation and comprises a serial number of a property right certificate) written into the property related important structural information and the second type information (such as property information data obtained by a house letter user, a developer, a second-hand house transaction broker, a house information consultant and the like) after fixed length calculation are packaged and combined to generate the property related important structural information.

Specifically, it should be noted that the fixed-length calculation of the second type of information (e.g., the house property information data obtained by the house information user, the developer, the second-hand house transaction broker, the house information consultant, etc.) may include the following ways, and one of them may be selected according to the actual demand condition:

the first mode is as follows: and merging all the second information, and performing fixed-length calculation on the merged second information. The second type of information is used as a whole, after the operation of a Hash algorithm, the existence certification of all the combined second type of information can be output, and the existence certification is written into important structural information related to the property as a part of the important structural information related to the property;

the second mode is as follows: and performing fixed-length calculation on each second type of information to obtain the existence certification of each second type of information, and merging all the existence certifications. Each piece of information in the second type of information is respectively and independently operated through a Hash algorithm, then respective existence proofs of all the second type of information are combined, and the existence proofs are written into important structural information related to the property and serve as a part of the important structural information related to the property;

the third mode is as follows: grouping all the second-class information, wherein the grouping rule can be determined according to the definition of product requirements, the correlation of information and the like, wherein each group comprises at least one piece of the second-class information, and at least one group comprises a plurality of pieces of the second-class information, for example, the second-class information is grouped; the second type information in the groups containing a plurality of second type information is merged, the merging step can not be executed for the group containing single second type information, the second type information merged in each group is calculated with a fixed length, the existence certification of the second type information in each group is obtained, and all the existence certifications are merged. The second type information is grouped according to a grouping rule, for example, the second type information is grouped, the information in the second type information group is merged, the operation is carried out by a Hash (Hash) algorithm by taking the group as a unit, then the respective existence proofs of all the second type information are merged, and the existence proofs are written into important structural information related to the property as a part of the important structural information related to the property.

Further, as the real estate related important structural information is generated in a large amount in a time-based manner, the embodiment of the invention collects and organizes at least one piece of real estate related important structural information into a new block according to a preset interval time and according to a processing capacity limit and the real estate related important structural information to be processed currently, so as to generate a new block; for example, when the preset time interval of the preset condition is 1 minute and one package is packed into a new block, the important structural information related to the property to be processed currently is 1w, and the processing capacity limit in the preset condition is only 6k, after the preset interval time is 1 minute, the important structural information related to the property collected and organized into the current new block is 6k due to the processing capacity limit in the preset condition, and the important structural information related to the rest 4k properties is collected and organized into the next new block; for another example, when the preset time interval of the preset condition is 1 minute and one package is packed into a new block, and the important structural information related to the property to be processed currently is 4k pieces, and the limit of the processing capacity in the preset condition is only 6k pieces, after the preset interval time is 1 minute, because the limit of the processing capacity in the preset condition is not reached, the important structural information related to the property organized into the new block currently is 4k pieces;

still further, the blockchain mining machine merges at least one property related to important structural information that has entered the new block, and in this process, a timestamp may be added to the generated new block, and the timestamp may be determined by merging and packing the start or end time of the at least one property related to important structural information, or by extracting the time information of the last property related to important structural information that has entered the new block as the timestamp; moreover, the signature can be executed on the important structural information related to each property and/or the integral signature can be executed on the new block so as to ensure the safety of the data in the transmission process; certainly, if a new block is successfully added to the blockchain, some other block control information may be needed according to the actual requirement of the blockchain, and those skilled in the art can freely add the new block according to the development requirement, which is not listed here. Thus, as shown in fig. 8, the new block may include at least one of the real estate concerns important structured information, timestamps, signatures, other block control information, and proof of existence of the previous block via a Hash (Hash) algorithm; still further, a fixed-length computation (Hash) algorithm) of the existence of the new block and the previous block is performed to link the new block to the previous block in the house letter credit central platform block chain.

In practical application, first-class information (important information related to house property valuation) marked with fixed-length type and importance degree attribute in house property information data takes house property certificate numbers as unique indexes and sequentially enters a house trust central platform block chain according to the acquisition time of the house property information data; in addition, the second type of information, which is identified in the property information data by the non-fixed length type and/or the importance degree attribute, may be referred to as other property information data, and may be stored in an out-of-chain storage system based on block chain existence certification, and the house letter packages the existence certification to calculate a Hash value (Hash algorithm), and adds the Hash value to the house letter credit central platform block chain.

FIG. 9 is a chain structure of the house property related to important structural information according to the sixth embodiment of the present invention. As shown in fig. 9, due to the inherent high transparency and non-information-falsification characteristics of the house trust center platform blockchain, it can be further understood that the property logically indexed by the house property certificate number as the unique index also forms a chained data structure with itself relating to important structural information, as distinguished from the chained structure formed again in the form of blockchain after being packaged in the block. Through the organization form of the house property information data, the house letter establishes a set of chained and generalized house property digital data records, and the chained data organization form enables a related house property database of the house letter to perform business verification on the reality and the reasonability of newly acquired house property information in a big data analysis mode from historical data. In addition to the inherent information of the house, the house trust system can also selectively add resident information, resident family information and the like from the aspect of information content, the non-tampering property of the data is ensured by adopting a block chain technology, the credibility of the data in the house trust house property database is greatly improved, and a foundation is laid for the house trust house property evaluation system.

According to the house letter system provided by the embodiment of the invention, the spare house property information data of the house letter credit central platform block chain is stored through the house property information data source; the real estate information data from the real estate information data source are collected and summarized by the real estate-related important structured information generation device; classifying the information according to the attribute of the property information data, and processing the classified different types of property information data; packing the processing results of different types of property information data to generate property related important structural information; the block chain mining machine organizes at least one house property related to important structural information to enter a new block according to preset conditions, and links the new block to a previous block in a house trust central platform block chain; the plaintext including the complex and variable length information is encrypted into a ciphertext through fixed-length calculation, and the plaintext of the fixed-length information and the ciphertext are combined to enter a block chain, so that the evidence storage and the non-tampering of the plaintext in the whole block chain are ensured; the complex and variable length information and the fixed length information in the plain text are classified and processed in a fixed length mode, the technical problem that the complex and variable length information cannot be processed by the existing block chain technology is solved, and the purpose that the complex and variable length information can be written into a block chain in a block mode is achieved.
